TROLLEY-WHEEL FOR ELECTRIC CARS.

To all whom it may concern:

Be it known that I, GEORGE C. S'rnA'r'roN, a citizen of the UnitedStates, residing at Camden, in the county of Camden and State of NewJersey, have invented a new and useful Improvement in 'llrolley-Wheelsfor Electric Cars, of which the following is a specification.

This invention relates to trolley wheels for electric cars, and has forits object to provide an improved trolley wheel by means of which thetrolley wheel will be prevented from straight course or on curves, orcrossing wires, and also by means of which the wheel and wire may bekept clear of ice and snow.

Referring to the accompanying drawings,

Figure 1 is a perspective view of the inventi on, Fig. 2 is an end viewin vertical section, 0 and Fig. 3 is a side view in vertical section.

In the construction of this invention, 1, 1, are the arms of the fork 2,of a trolley-pole 3, the arms 1, 1, carrying a shaft 4, provided with anumber of radial arms 5, rigidly secured upon the shaft by the cotterpins A constituting a protector for the trolley wheel, as hereinafterset forth.

6 is the trolley wheel, loosely mounted on the shaft 4, and locatedbetween the radial arms 5. The radial arms 5 are arranged in pairs eachhaving the straight member 7 extending the diameter of the trolley wheel6, and a curved member, 8, at each end, having an inner curved shoulder9 in front of the edge of each rim 10, of the trolley wheel 6. By meansof this construction the inner curved faces of the pairs of members 8will e opposite each other and the rims 10 of he trolley Wheel willrevolve inside of the urved shoulders 9.

The trolley wheel and protector are made f suitable conducting metal.

In use the curved members 8 are always up bove the Wire so that it isimpossible for the 'olley Wheel to get off the wire. In going out curvesthe wire will be at one side of ie trolley wheel and the wheel will berejumping or leaving the wire, either in a Patented May 12, 1908.

tained. in place by the shoulders 9. The protector enables the trolleywheel to pass smoothly over crossing wires. In crossings, and at angles,the protector will rew olve so as to strike a cross wire or smooth wireor switch plate and enable the trolley wheel to clear smoothly and stillbe retained 011 the wire. If for any reason the wire is brought abovethe shoulders S), the curved members 8 will retain the wheel on thewire.

To reduce friction, the shaft 4 may be provided with ball bearings 11,as shown, and ball bearings 12 may be located between the wheel 6 andthe arms 5.

By means of this invention the wheel can never get oil the wire,constant and perfect contact is assured, and the wheel accommodatesitself to all conditions of curves, crossings, etc. The radial arms ofthe protector serve to remove ice and snow from the wire.

II aving thus fully described my invention, what I claim as new anddesire to be secured by Letters Patent, is:

1. A combined trolley wheel and protector, consisting of a trolley wheelloosely mounted on a shaft between pairs of radial arms fixed to saidshaft, and having curved projecting ends extending beyond the pe ripheryof the wheel, and curved shoulders projecting over the periphery of thewheel, as set forth.

2. A combined trolley wheel and protector, consisting of pairs of radialarms fixed on a shaft, and a trolley wheel loosely mounted on said shaftbetween the radial arms, the latter having opposite curved shouldersextending inwardly over the periphery of the wheel, and oppositelycurved end portions extending from the curved shoulders, as set forth.

In testimony whereof, I have hereunto signed my name in the presence oftwo sub scribing witnesses:
